huey45 Posted April 19, 2017 Share Posted April 19, 2017 Hi I want to replace all outside none LED standard bulbs, on my car and caravan to LED types as my car is fitted with CANBUS system, is there any way to go into FOCCCUS 0.8.5 system to disable bulb checks ?? which would stop errors being thrown up at me... 2015 Ford Focus Mk3.5 Titanium Quote Link to comment Share on other sites More sharing options...
JW1982 Posted April 20, 2017 Share Posted April 20, 2017 The complete bulb check system can not be deactivated. It is only possible to deactivate the bulb check system of the low beam bulbs by configuring the headlights as "Alternative HID". This configuration setting deactivates the bulb check system of the low beam bulbs and changes the PWM supply to a steady 12 V battery supply. Note that not all bulbs are monitored by the bulb check system. many light bulbs can be changed for LED's without any problem. To check which bulbs are and which bulbs are not monitored you can remove them one by one and see if the removed bulb generates a warning message onto the instrument cluster display.

Gizza11 Posted April 20, 2017 Share Posted April 20, 2017 You can get led replacement bulbs standard and uprated type that are canbus friendly (I think they have a resistor in them so that they match) that way you won't need to do anything. I have some canbus friendly leds on mine and I have no issues at all with the bulb checker. I got mine from Halfords but have seen them on eBay too.
